The Quality of Service (QoS) is a network-attached program specifically for Windows XP Professional users, and the system defaults to calling this program when you install Windows XP. For individual users or campus network users, this program is not practical significance, but also occupy

Author: Cen- Windows Network Programming MiscellaneousBIND: inaddr_any is bound to 0.0.0.0. In this case, all addresses are valid. If the system considers redundancy and uses multiple NICs, bind will be bound to all NICs. In this case, you can receive packets sent to all valid addresses. Example: sockaddr_in local; local. sin_addr.s_addr = htonl (inaddr_any ); Another method is as follows: sockaddr_in local

Speaking of Windows Application Layer network communication has to mention Winsock,winsock is working in the TCP/IP layer of the application layer (TCP/IP layer is divided into host to network layer "bit", Network interconnect layer "data frame", Transport Layer "packet", Ap

Traditional packet capture tools in windows, such as Wireshark/ethereal, cannot capture packets for network communication between local programs. Some commercial packet capture tools use Winsock LSP (Layered Service Provider) the technology implements packet capture for

Due to the need for work, in the wondows often use some commands to determine the cause of network environment failure, now the commonly used commands summarized as follows (at the cmd command prompt):Ping is used to test the connectivity of the current network environment,-T: With this parameter can ping each other's host, such as: Ping 192.168.1.1-t-L: With this parameter, you can set the size of the send
